North Korean leader Kim Jong-un and his wife Ri Sol-ju appeared at Kumsusan Palace of the Sun on Sunday to pay their respects to his grandfather and regime founder Kim Il-sung and father Kim Jong-il.
Ri made her first public appearance in 40 days since a concert celebrating the New Year on Jan. 1.
Ri, clad in a black, two-piece dress, was noticeably thin, leading to consolidating the speculation that she gave birth in late 2012. She had appeared pregnant in photos even until mid-December, but her belly seems to have gone flat by the New Year's concert.
"North Korean authorities may have either induced Ri to go into labor at the end of last year or have her child through caesarean section in order to bear a child in 2012, which marks 100 years since founder Kim Il-sung's birth," one South Korean government source said.
Meanwhile, various ceremonies were held in North Korea on Saturday to mark the 71st birthday of Kim Jong-il.
